Porsche V10 engine

The Porsche V10 engine is a naturally aspirated ten-cylinder piston engine that Porsche designed as a concept for Formula One racing in the 1990s and then for Le Mans racing, before it became the powerplant of the Carrera GT supercar. It descends from the unsuccessful 3.5 litre V12 that Porsche had built for its early 1990s Formula One effort, with a V10 replacement still in development when the company withdrew from the sport. The engine was reworked for the stillborn LMP2000 prototype and finally built as the 5.7 litre 68 degree unit with aluminium block and heads, titanium connecting rods and variable intake valve timing, rated at 450 kW and fitted to the Carrera GT from 2003 to 2007.
